Ole Gunnar Solskjaer piled praise on his players after they claimed bragging rights in the Manchester derby.
Goals from Anthony Martial and Scott McTominay secured a third win of the season over their rivals as Ederson endured a nightmare in the Man City goal.
The 2-0 win at Old Trafford extended United's unbeaten run to 10 games in all competitions and Solskjaer was beaming after the game
He told Sky Sports: "The desire, attitude, commitment, connection between fans and players pleased me most.
"At times we pressed them, pushed them back, we tried to be aggressive. We made them make mistakes and we are happy with the result.
"It is a privilege to be a manager of a squad with this attitude. You can't ask for more. They are going to improve as players as well.
"Those little things will come but it is a privilege and they want to listen to advice. For our players to beat a team like Manchester City is fantastic, I am delighted for them."
McTominay added: "That was such a sweet moment. Credit to the boys. Sticky first 20 minutes and we had to keep going.
"We will take confidence from that but in the coming weeks we have got to keep the run going.
"It's such a beautiful feeling to score like that in front of the fans. But we can’t get too carried away and need to keep pushing for the Champions League."
City manager Pep Guardiola admitted his side should have prevented United's opening goal.
He said: "We conceded a goal and we should avoid it. We knew Fernandes sometimes is chipping the ball."
Asked about Ederson's mistakes, Guardiola responded: "He's an exceptional goalkeeper. I'm not here to judge my players. He will recover and he is a special talent."
